V922

I’ve been looking the best way to place the Brushless main motor on my frame and if you’ve been reading a bit, some spacers are needed to avoid the servo boards touching the main motor. At first I tried with the empty tube of a BIC pen..

but was so big so I decided to look for a smaller one..lollipops sticks, cotton ear cleaners (smaller) and finally I found the perfect source for spacers at 0$ cost… Wires !!! yes, we need a small gap of 0,6-0,7 mm between the servo pcb and the main motor so just take a piece of wire and peel it of, the plastic tube fits perfect.

After putting the spacers on the boards I put them back into the frame, the gap was ok, main motor not touching the pcb

Then is soldered the Dual ESC to the main board using the next diagram (Thanks Daryoon from Hacksmods blog)

You must use a very thin solder, mine its a Spike operated by 3 AA batt.

I’ve not pictures of the ESC attached to the main board, sorry but my camera ran out of battery …. :(

I turned the transmitter on, put the battery (The heli was without blades to avoid any damage…) I heard the sweet music from the ESC… and voila everything working…but now the bads news :(:(:(

After a whiles the motor stop, I was worried about the FETs so i checked ’em, FETs Ok so let’s try to spot the problem…..

The problem seems to be the main board, it can’t stand too much current drawing so if i put the tail motor off, everything works (I noticed a small delay the first time you push the throttle, I thinks it could be a kind of safety mechanism, next time the motor starts ok).

Conclusion, I feel sooo sad :( , I think HobbyKing Dual ESC it’s not a good choice, I’ll rather wait for the Air Base setup (only main motor) from Miracle Mart (currently out of stock) because I’ve read it works better and it’s smaller than HK Dual ESC…

Want to take out the slop? This kit it’s the solution (thanks John for giving me the oportunity to test the kit )

KZALASKA sells this kit for the MCPx but since MCPx and the V922 have a lot of parts in common they could be used whitout mod. anything.

It takes only a few minutes to install, you get 13 O-Rings (Silicone) just for 3,50$.

I’ve installed them into my V922 and the results are great!, more control on stick movements,They take out the play at the ball joints reducing vibrations and give smoother stick inputs

Here are the pictures…:

The kit comes with clear installation pictures so the process its a piece of cake.

The O-rings out of the plastic bag.

First O-Ring in place.

They fit perfectly.

Finished

I have not used the skids O-Rings because I’ve found another use for ’em… Take the slop out on my V911 !

If you own a V911 you’ve noticed that it has a big “pendulum” effect, using the O-Rings that effect will be reduced a lot, another good mod to reduce the effect it’s moving the battery forward to move the CG.

O-ring kit takes the slop out of the blade MCPX’s Head Upgraded Dampners improve the blade dampening between the Blade Grips and the Rotor Head Adds GRIPTION to your skids so you don’t slide much while spooling up on the ground

Hi, sometimes it’s hard to see the heli due canopy / blades colours. To make it more visible I’ve changed the stock canopy (Blue one) for a Hisky FBL100 “Cool Green” . The main and the tail baldes have been replaced too.
